• controller 100 may also instruct display device 124 to display an image and/or video showing the detected objects captured by sensor 130 (e.g., a video camera located on a side mirror 30 in Fig.2) so that the operator may be notified of the positions of the objects. Additionally or alternatively, controller 00 may display a message and/or actuate an alarm via I/O interface 104 or alarm 121. [0038] At 1030, controller 100 and/or sensor 130 may determine whether the detected object is (or will be likely to be) within a projected path of the door as the door moves from its original position to an open position. The projected path can be determined based, for example, on the dimension of the door and the maximum door opening angle.
• system 10 may activate one or more of actuators 22 to move the door from the closed position to the open position (at 1050).
• system 10 may modify the movement of the door. For example, controller 100 may instruct control interface 120 to control one or more of actuators 122 (at 1040) to stop moving the door. In some embodiments, controller 100 may instruct a blocking mechanism (not shown) to stop moving the door.
• controller 100 may also instruct control interface 120 to control one or more actuators of 122 to move the door back (or towards) its closed position (i.e., closing the door). In some embodiments, the door is not moved at all. In some embodiments, controller 100 may also actuate an alarm, via I/O interface 104 and/or alarm 121. Additionally, or alternatively, controller 100 may also instruct display device 124 to display an image and/or video showing the detected object, as described herein. In some embodiments, controller 100 may further notify the operator that the door may not be moved because one or more objects are within the projected path of the door, and wait for further instructions from the operator.
• the notification may be provided by, for example, displaying a message on display device 124, actuating an alarm via I/O interface 104 and/or alarm 121. The operator may then manually pull the door to a desired position, in order to avoid the contact of the door with the object(s).

• sensor 130 may measure a distance between the object and the door (and/or the vehicle). Merely by way of example, the distances between several points on an object and several points on the exterior of the vehicle door and or vehicle may be determined. The determined distances may be compared, and the smallest distance may be used in further processes including, for example, determining whether the distance is equal to or smaller than a threshold distance, as explained in more detail herein.
• sensor 130 may measure the distance based on the reflected signal (radar, light, and/or ultrasonic signal) received and/or an image captured by sensor 130.

If the distance(s) is/are equal to or smaller than the threshold distance, at 1040, system 10 may modify the movement of the door, as described herein. On the other hand, if the distance(s) is/are larger than the threshold distance, system 10 may not modify the movement of the door and initiate opening of the door (at 1050), as described herein.
• sensor 130 and/or controller 100 may determine whether the detected object is moving.

On the other hand, if the object is moving, sensor 130 and/or controller 100 may determine a moving direction of the object (e.g., moving towards or away from the vehicle) and/or a speed at which the object is moving. Sensor 130 and/or controller 100 may further determine a distance between the object and the door (and/or the vehicle), and/or determine whether the distance(s) is/are equal to or smaller than a threshold distance, as described herein.
• sensor 130 and/or controller 100 may determine whether the object will be likely to be within a projected path of the door as the door moves from a closed position to an open position based, at least in part, on the distance between the object and the door (and/or the vehicle), the moving direction of the object, and/or the speed at which the object is moving. If it is determined that the object is unlikely to be within the projected path of the door, system 10 may not modify the movement of the door (at 1050) and initiate opening of the door. On the other hand, if the object is likely to be within the projected path, system 10 may modify the movement of the door (at 1040) as described herein to avoid contact with the object.

• controller 100 may generate a second control (at 2050) signal indicative of a destination position to which the door is to be moved and transmit the signal to control interface 120 for controlling one or more of actuators 122 to cause the door move to that position along a second projected path (at 2060).
• the destination position to which the door is to be moved may be predetermined. For example, if the door is open and the operator indicates that the door is to be closed, the destination position may be the closed position of the door (e.g., the door is completely closed).

On the other hand, if it is determined that the object(s) remains/remain within the projected path (or a new object is detected within the projected path), controller 100 may Instruct control interface 120 to control one or more of actuators 122 to stop moving the door (2090). Alternatively, controller 100 may perform steps 2030 and 2040 as explained herein.

• the door may be slowed in the powered mode and/or in the manual mode (e.g., progressively slowed until a threshold distance is reached, at which point the door is stopped completely).
